Switchable Photoelectrochemistry in Thin Films of SbSI Microrods

Solar RRL, Volume 10, Issue 7, 15 April 2026.
Thin film electrodes consisting of SbSI microrods demonstrate photoelectrochemical properties that can be tuned by adjusting the film thickness, pH of electrolyte, and O2 concentration. The performance of SbSI electrodes can also be switched by changing the temperature and thus employing the ferroelectric transition.

Influence of Surface Area Calculation Methods on the Interpretation of Lithium‐Ion Diffusion Coefficient in Graphite Electrodes

ChemElectroChem, Volume 13, Issue 7, 1 April 2026.
Accurate determination of the lithium‐ion diffusion coefficient requires a consistent definition of active surface area. Applying galvanostatic intermittent titration technique and intermittent current interruption to a commercial graphite electrode, we quantify how three common approximations—geometrical area (AGA), scanning electron microscopy ...

Impact of Electrolyte Temperature on Solution‐Combustion Synthesized NiO/Ni Nanoparticles as Oxygen Evolution Reaction Electrocatalyst

ChemistryOpen, Volume 15, Issue 4, April 2026.
Electrolyte temperature significantly affects electrocatalyst performance in water splitting reactions. Catalysts synthesized by solution combustion synthesis were evaluated for oxygen evolution activity at different temperatures. Elevated temperatures reduced overpotential and increased current density, reflecting enhanced reaction kinetics and ...
